    Abstract: A vehicle lamp which includes a reflection mirror, a front lens, and a light source arranged between the reflection mirror and the front lens. The central axis of the light source is perpendicular to the principal optical axis of the reflection mirror. On the reflection mirror, there is formed a reflection surface composed of a large number of reflection steps which are defined by portions of paraboloids of revolution and are formed between adjacent ones of closed curves. The closed curves are obtained as lines of intersection between a fundamental reflection surface and a group of paraboloids of revolution composed of a large number of paraboloids of revolution having different focal distances. Centers of the group of closed curves forming the boundaries of the reflection steps are arranged at a position distant from an intersection at which the principal optical axis of the reflection mirror crosses the reflection mirror, and square lens steps are formed on the front lens. Due to the foregoing, the arrangement of the image of the light source that has been projected by the reflection steps tend to be matched with the sections of the lens steps formed on the front lens.
